Statistical properties of He-Ne laser radiation reflected through a turbulent atmosphere
Abstract
Statistical properties of a He-Ne laser beam (0.63 micron) propagating through atmospheric folded paths of 1 and 12 km were investigated experimentally using direct and heterodyne detection. Measured scintillation histograms, power spectra, time autocorrelations, and phase fluctuations are reported. The turbulence parameters derived from the optical measurements were found to be in good agreement with those obtained from measurements of in situ temperature fluctuations.
